Answer:Genes that are located on the same chromosome are called linked genes. Alleles for these genes tend to segregate together during meiosis unless they are separated by crossing over. Crossing over occurs when two homologous chromosomes exchange genetic material during meiosis I.
so true
Explanation:
Answer:
Start your seeds off indoors - they need plenty of warmth to germinate.
Fill a seed tray or some 10cm pots with moist seed compost and flatten down.
Sow a few seeds on top and cover with a fine sprinkling of vermiculite or compost.
Place in a propagator at a temperature of 18-25C (64-77F).
This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.
My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.
This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.

Second level consumer: 100 energy units
Third level consumer: 10 energy units
Explanation:
Determination of specific cells for certain functions changes resulting from induction the occurrence of mRNAs for the production of tissue-specific proteins changes in the size and shape of the cell cell.
